HP Network Node Manager Command Injection Vulnerability

01.10.11

BACKGROUND

HP Network Node Manager Command Injection Vulnerability HP Network Node Manager (NNM) is an application suite that is used to map out and manage network topography. NNM runs on a variety of platforms, including Linux and multiple versions of Windows. For more information, see the vendor's site found at the following link: http://www.openview.hp.com/products/nnm/index.html

DESCRIPTION

Remote exploitation of a command injection vulnerability in Hewlett-Packard Development Co. LP (HP)'s Network Node Manager could allow an attacker to execute arbitrary commands with the privileges of the affected service. The vulnerability exists within CGI scripts provided with the NNM HTTP Server. These scripts do not effectively sanatize a particular parameter. It is possible for an attacker to supply a parameter containing a specially crafted command line string. The command line string will be executed on the affected NNM HTTP Server.

ANALYSIS

Exploitation of this vulnerability results in the execution of arbitrary commands with the privileges of the affected service. On RedHat Enterprise 4, the application is started as the user 'bin.' By default no authentication is required.

DETECTION

OpenView Network Node Manager versions 7.51 and 7.53 running on HP-UX, Linux, Solaris, and Windows are vulnerable.

WORKAROUND

By default the affected CGI scripts do not require a user to be authenticated. Authentication can be enabled on the NNM HTTP Server. For further details refer to the NNM "Managing your network" guide.
